If a browser is installed for general use, it can be used to access the general Wikipedia site, also for editing, depending on limitations of the browser. One may want to adapt the user style and preferences to optimize them for the mobile device. For example, navigation popups may or may not be convenient on the mobile device.

The mobile version is available for all versions of Wikipedia. It is actively developed, supported and translated. Editing is not yet possible and you might want to use a third party solution as an alternative. If you don't like using the mobile interface, you can navigate to the actual Wikipedia or choose to disable the mobile interface permanently on your device. You can find these options at the bottom of any page. If you have permanently disabled the automatic redirect to the mobile interface and have since changed your mind, you can use the activation page, to restore the automatic redirect behavior. (Note: some users have reported that the activation page does not work for them). [1]

Some of the key features that are still missing in the mobile gateway experience include:

Editing

Image Uploads

During Q2 2011 the WMF halted all new development work and undertook a project to port the existing Ruby gateway to a MediaWiki extension to simplify the operations infrastructure. This project replaced the existing Ruby gateway for all functionality and full deployment was completed on 12 September 2011.

The official iPhone application from the Wikimedia Foundation is Wikipedia Mobile. It is free and provides a read-only version of Wikipedia, that is very similar to the mobile web version of Wikipedia. It also allows you to find geotagged articles near your current location.

Amazon Kindle (3G versions) have the free access to Wikipedia content through mobile phone network on the "experimental browser" included in Kindle software. All content is shown in black-and-white (all colored images and graphs are converted).

One of the most prominent Wikipedia portals for mobile devices is Wapedia. Having started in August 2004, Wapedia offers the recent version of every article. Next to Wikipedia, it can provide access to the sister projects Wiktionary, Wikiquote and many other popular wikis. Wapedia pages currently contain advertisements inserted by the site's owners.[2] It supports a wide range of devices and even some of the oldest mobile devices can be used to access Wikipedia through this website.

Sevenval AG offers a free real-time transformation of the current Wikipedia. The link to the service is http://wikipedia.7val.com. It offers a full-blown version of Wikipedia for all kinds of mobile devices. This enables mobile users to edit articles and administer their personal accounts. Wikipedia's sister projects – Wiktionary, etc. – can be accessed via this service as well. 50 languages of Wikipedia are supported. [3]

The following features are currently available.

Device recognition of mobiles, smartphones, PDAs, etc., which enables the individualized adaptation of the presentation transmitted to different types of devices.

A free real-time mobile-adapted Wikipedia browser provided by HAWHAW at http://mobile.wikipedia.org minimizes images and presents article text in pieces of approximately 7kb to facilitate transfer. In standard browser, often hundreds of kb are transfered when opening an article. HAWHAW is suitable for slow or expensive Internet access, as well as devices with a small screen, but may well be used in all conditions to get a quick introduction to various concepts, which is usually provided in the first 7kb, making downloading of further pieces mostly unnecessary.

HAWHAW stands for HTML and WML hybrid adapted Webserver

It does not give spelling suggestions for slightly misspelled terms, and does not support tables.

A computer-generated audio (speech synthesis) version of all Wikipedia articles is provided by the Pediaphon service. It is usable on- and off-line with common MP3 players, PDAs, cell phones (WAP) and with every phone via voice call. Pediaphon can be used as a location-based service.

Automatic conversion from HTML to WML is not really a «version» of wikipedia, but is still worth mentionning. Some projects offer transcoding software (e.g. Coldjava's h2W servlet), while others offer the transcoding online and on the fly (e.g. BabelServer).

Many iPhone applications exist for browsing Wikipedia. All the applications so far are read-only versions of Wikipedia. Currently, the only way to edit Wikipedia on an iPhone is to access it via Safari. The links will open the iTunes Store:

A read only version of Wikipedia is available at http://wikipedia.boopsie.com/. This mobile phone download supports BlackBerry, Windows Mobile, Palm OS, Symbian S60, J2ME, Android, and iPhone. (A BREW version is available but must be side-loaded.)

WikiPock is a mobile application that provides offline access to all Wikipedia articles in 22 languages for Windows Mobile, BlackBerry, Android and Symbian OS mobile phones. All the articles are stored in the mobile phone's memory.
